Further, the invention relates to a method for the performance of an automatized change of rollers for a winding machine, a device for the performance of an automatized change of rollers and a film production device.
- films are produced as endless material and are wound up on receiving means (for example sleeves) in winding machines. After the desired film length was wound up to a receiving means, a change of rollers is performed. To do this, the film has to be separated and wound up to a new receiving means.
- receiving means for example sleeves
- the object of the present invention to at least partially avoid the previously described disadvantages. Particularly, it is the object of the present invention to enable a reliable fast and/or cost-efficient change of rollers for a winding machine.

- the adhesive means layer preferably comprises an average thickness of maximum 2000 ⁇ m in order to mainly maintain the structure of the surface region during placing and/or after placing to the transport device.
- the receiving means can, for example, be configured as a sleeve for the winding machine, particularly a paper sleeve.
- the structure of the surface region of the wall can be affected for example by the fact that parts of the receiving means like the outer paper layers (paper sheets) are at least partially detached. Due to the reduction of the average thickness of the adhesive means layer, however, the adhesion can be reduced particularly a stickiness or adhesive strength such that the structure of the surface region is mainly maintained and/or during application no affecting contamination of the surface of the transport device occurs, particularly of a contact roller.
- a further advantage for the change of rollers results particularly by the fact that the receiving means can be automatized prepared with an adhesive means for the configuration of the outer adhesive means layer.
- the adhesive means layer thereby preferably comprises all adhesive means regions at the surface region and/or at the receiving means.
- the remaining regions or areas of the surface region outside the adhesive means layer are preferably free from adhesive means and/or contact-free.
- Contact-free means that these areas only contact the surrounding (surrounding air) towards the outside (and therewith not the adhesive means layer) and accordingly configure the outer layer or surface of the receiving means.

- the adhesive means can be suitable for a processing temperature which is in the area of 100° C. to 250° C., particularly 140° C. to 170° C.
- an adhesive means layer can be generated which comprises such a small stickiness that during application of the receiving means with the adhesive means layer to the surface of the transport device no essential detachment of parts of the receiving means occurs.

As soon as the beginning of the film contacts the prepared receiving means the film material or the beginning of the film sticks to the adhesive means and is transported along with the receiving means. Hereby, a winding or winding of the film material at the receiving means occurs.
- the method according to the invention particularly enables this winding without the need of a lifting of the film material from the transport device, particularly a contact roller.
- an automatized preparation with the adhesive means can occur such that no expensive and elaborate adjustments of the used sleeve have to occur.
- the application of the receiving means prepared with adhesive means to the transport device occurs preferably film-free, meaning that no film is existent between the prepared receiving means and the transport device during application.
- a receiving is used with a sufficiently rigid wall and an adhesive means adjusted such that during application and/or after application to the transport device the structure of the surface region is mainly extensively preserved, meaning particularly that mainly none of the uppermost layers of the receiving means are detached, particularly the paper layers.

- the application of the receiving means according to step C occurs directly to the transport device, particularly by contacting the transport device.
- the receiving means contacts at least partially the film material, particularly the beginning of the film, during application. Therefore, the application has to be coordinated such that when the beginning of the film arrives in the nip the application occurs at the same time, meaning the contacting of the receiving means with the transport device and/or with the film material or the beginning of the film occurs at the same time.
- the application occurs therewith preferably during a contacting of the transport device and the beginning of the film or alternatively only during contacting of the transport device without contacting the film material at the same time.
- a certain tolerance can be accepted such that an exclusive contacting of the receiving means with the film material occurs without contacting the transport device.
- the application of the receiving means to the transport device occurs mainly (meaning also completely) contactless to the film material according to step C.
- the area between the transport device and the receiving means is mainly free from film material during application.
- the contact roller is thereby preferably configured as a VSK-roller (vacuum-cutting-contact roller) in order to provide an improved cut for the generation of the (new) beginning of the film during the change of rollers.
- the application of the receiving means to the transport device according to step C can occur only by contacting the transport device and/or only by contacting at a contact area of the film material in which the film material abuts at the transport device.

- a contamination of the transport device by releasing parts of the receiving means is avoided.
- the preparation of the receiving means occurs as a large scale, particularly full scale, application of the adhesive means, particularly such that a thin adhesive means layer covers at least largely or completely a surface region, particularly a side area of the receiving means.
- the largely preparation can preferably occur by an automatized spraying or wetting of the surface of the receiving means with the adhesive means. With a largely preparation thereby mainly the complete surface (side area or surface region) of the receiving means is provided with adhesive means.
- a reliable receiving of the film material at the receiving means according to step C can occur.
- the adhesive means comprises in average a thickness of maximum 2000 ⁇ m or maximum 1000 ⁇ m or maximum 700 ⁇ m or maximum 300 ⁇ m.
- the average thickness can be, for example, in the area of 2 ⁇ m to 2000 ⁇ m and/or 5 ⁇ m to 300 ⁇ m and/or 100 ⁇ m to 200 ⁇ m.
- step B for the preparation of the adhesive means occurs such that only a preparation region comprises an adhesive means layer and/or an edge region of the receiving means or the surface region is left out during application.
- a defined edge distance of each beginning and end of the receiving means meaning particularly of the opposing lateral regions, can remain without adhesive means and/or can be left out during application.
- the preparation region thereby corresponds particularly with the area at which a winding with film material occurs.
- the edge region can be configured as a defined edge region preferably in the lateral region of the receiving means (meaning for example in the area of the sleeve beginning and sleeve end) particularly preferred without adhesive means.
- an optimal result during winding is ensured.
- step B for the preparation an application of the adhesive means occurs as an adhesive image, particularly in a spiral form and/or circular.
- the adhesive image can thereby be configured as a combination of multiple forms (for example, partly circular or partly spiral-like) and/or comprise at least one edge region which is free from adhesive means.
- the adhesive image is produced using a (particularly digital) template.
- the generation of the adhesive image can for example be controlled by a control device which, for example, controls an application device for the application of the adhesive image according to step B.
- This template can, for example, comprise the exact form of the adhesive image, for example, as a digital image and/or coordinate specification and/or parameter for the adhesive image like, for example, a respective inclination of the spiral. Therewith an optimal result during the winding of the film material can be achieved.

- the adhesive means particularly a melt adhesive, preferably a hot-melt adhesive, can be applied in a heated state to the adhesive area, meaning to a surface region of the receiving means according to step B.
- the adhesive means can be existent, for example, as a granulate or powder or film or rods or in block shape in the none-heated state previous to the application, wherein by the application device a heating of the adhesive means occurs directly previous to the application. Thereby, a heating to, for example, a temperature in the area of 150° C. to 200° C., preferably mainly 160° C. occurs.
- the adhesive means for example, comprises polymer (like polyamides, polyethylenes and/or polyester) and possibly a resin and/or a stabilizer and/or wax.
